signal is not good enough and percentage is only 25% or 50%. If 3G network percent is below
75%, it is not good enough to transfer video file, user should change to other place for better
mobile 3G signal or change to use WIFI signal. Moreover, 1 device can send push notification
ring to max. 5 mobile phones at the same time, user should set more mobile phones to receive
the push notification ring to avoid this 3G signal not good at some places problem.
